Q & A

Collects Specimens for Lab Testing
Nurse collects blood and prepares the samples
for testing.
APIs are Transforming Healthcare
Maria
A mother of two kids; Very focused on family’s
health; Looks online to support family’s well being
Maria is testing her 10-year old daughter for
allergies and schedules an appointment
Maria wants to monitor her daughter test
results; takes actions based on results
Maria receives her daughter’s test results with
details through email/SMS
Testing done in Quest Lab
Maria checks-in Quest Lab
for her daughter’s testing
Behind the scenes, all interactions are performed using APIs. An API does this by 'exposing' business functions through Interfaces.
Thus facilitating an improved customer experience.

6. Challenges in building Healthcare Integrated Experience
1.How to quickly deliver the business values.
2.How to build seamless integration with partners.
3.How to manage and support APIs at large scale.

7. API Value Chain
Discover APIs
Business Service
e.g. Lab Testing Appointment
Scheduler
Design API so target
audiences can use.
Customer
Partner
3rd Party Provider
• API Value Chain starts with customer pain points, identify business assets; data source, something that a
business wants to allow others to use to solve customer problem.
• API is the interface to value proposition.
• Customer centric mindset leads to outside-in thinking – that leads to integrated customer experience.
• And that’s how API can drive new business growth.
• Internal Developer
• External Developer
• Partner Developer

8. • APIs are a way to connect business units together to
expose business capability to drive growth.
• Focus should be on API consumer.
• APIs are the interface for enabling API Value Chain
• They must be designed in such a way that they are
easy to discover.
• API Governance is the process of managing decision
making and decision implementation
API Drives Business Growth
• Identify business services/assets.
• Understand customer/partners needs.
• Start with API as a Product mindset instead of individual
APIs;
o This will help to deliver business outcome faster.
• Build easy to discover, easy to consume, reusable, secure
API Products
o Optimize the build cost.
• Establish API Governance to bring consistency in API
Lifecycle management.

9. Private APIs
APIs Types
Partner APIs
FIHR APIs
FHIR Source: https://www.hl7.org/fhir/
https://cloud.google.com/healthcare-api/docs/concepts/fhir
Erik Wilde - https://www.youtube.com/watch?v=jH_P699T1S4
• FHIR APIs define the layer on top of an EHR (Electronic Health Record), that allow other applications to interact with
its data.
• FHIR is an information network that lets you link data across systems and a communication network that lets you
exchange data between systems.
• FHIR includes an HTTP-based RESTful protocol
• Data representation uses JSON Format
— Private APIs are for in-house
application development, for an
organization and it's employees.
The need is private to an
organization.
– These APIs could internal or
external
– Improves system connectivity
— Partner APIs are only available to
partners after contractual
agreements. Restrictions apply
– This are external APIs for
partners usage
– Improves partner relationship
Public APIs
— APIs are publicly available. These
are easy to use for App
developers/API consumers
– These APIs are external
– Brings new business model

10. What is API
Discovery?
API Discovery is the ability of quickly finding APIs.
A way to break API Silo to improve API Adoption
and API Security.
Discovers what kinds of sensitive health data the
APIs can access.
Find the “right API product” for developers and
ensure it’s maintained and secure.
API Discovery is an element of API Lifecycle
management and API governance.

11. Lack of
API Visibility
Inconsistencies
In API Design
Higher Build and
Maintenance
Cost
Increase
Complexity
In Decision
Making
Conway’s Law: Any organization that designs a system will produce a design whose structure is a copy of the
organization's communication structure
Scaling is the challenge – API Duplication

— API Governance helps
your teams to make
better API decisions
— Helps to bring outside-

— Improves API
Developer experience
— Increase API Adoption
— Improve API Insights
— API documentation is
the first interface for
app developers to learn
about API
— For Health API - FHIR
standard
— API Developer Portal –
where developers can
find APIs
— Easy to onboard and train
consumers to use API the
“right way”
— Ensure API
documentation is up-to-
date.
— Easy to follow and easy
to use API products
than individual APIs
— Helps to identify API
security issue
— Improves API
Consumptions model
— Improves customer

14. Key Takeaways:
1.APIs are transforming HealthCare customer experience. They are the
connecting tissue of digital value chain.
2.For successful API Adoption, its important to quickly discover APIs.
So, focus should be on API Consumer.
3.API Discovery is an element of API Lifecycle management and API
Governance.
4.API Governance is the heart of API Management. It's all about
continuously observing decisions and making improvements.
